I've been searching for the title of this movie I watched a while back when I was a kid, but I don't remember much about it.
The movie was black and white, and has a spaceship that either lands or crashes on Earth, I think in a city. The door opens and a man comes out; people were expecting an alien but it was a human being. He explains something about leaving Earth years earlier but since he was traveling, at the speed of light I guess, he didn't age at all.
The next thing I remember is that someone was chasing him and shooting at him. He gets shot in the leg and since he's wearing a suit, somehow he clicks something on it and it makes him invisible... That's all I remember.
